Protecting People, Products and Critical Infrastructure

A History of Innovation

Air Techniques International (ATI) is a leading designer and manufacturer of specialized testing equipment for HEPA filters, media, filter cartridges, respirators, and protective masks. ATI offers a comprehensive portfolio of products ranging from small portable units for on-site certification to large systems used by major producers and test laboratories. ATI’s solutions include HEPA filter leak test equipment used to test and certify pharmaceutical and medical cleanrooms, containment facilities, and biosafety cabinets. Other solutions include automated filter testers used to test flat sheet media, respiratory PPE for occupational health and safety standards, and filter cartridges for nuclear, life sciences, pharmaceutical, biosafety, and defense applications.

Since 1961 with the introduction of the world’s first portable photometer for cleanroom certifications to the present with the launch of a real-time biodetection sensor, ATI remains a front-runner of innovation. Our latest offering, the Polaron^®, continuously monitors the air and provides early-warning alarms of potential aerosol threats. The Polaron can detect and classify aerosol particles as small as 0.5 microns, making it ideal for a variety of critical detection applications. 

In 2016, ATI acquired DOP Solutions, a UK-based company with over 25 years of experience in the industry. This strategic acquisition enabled ATI to establish local operations in the UK, providing better technical support and service to our customers and partners within the EMEA region. The UK applications team is well equipped to provide guidance on special projects and conduct local training and certification classes.
